Astrophytum asterias cv. OOIBO KABUTO (Japanese selection with wide
areoles)
|
|
A. asterias cv. OOIBO KABUTO is a Japanese selected
strain with big areoles.
The "OOIBO" is very similar to the common A. asterias,
but it has very large characteristic and woolly areoles, the colour of
the wool also varies from pure white, to pastel, yellowish, orangish or
brownish depending on the clone. So it is easily distinguishable from
the standard A. asterias that has relatively small
scarcely woolly greys-white areoles.
Remarks: This is one of the most famous and
peculiar Japanese Astrophytum cultivars.

However the large areoles "trait" can be appear in combination with
other A. asteris cultivars, for example it can be found in
A. asterias nudum (this combination may be named

Scientific name:
Astrophytum asterias
(Zucc.) Lem
cv. OOIBO KABUTO (Large areoles type)
Origin:
Garden origin (Nursery
produced cultivar)
Conservation status: Listed in
CITES appendix 1
Cultivation remarks: It is
not too difficult in a
greenhouse, although it grows quite
slowly. The plants need a loose well-drained
mineral soil. They need a good amount of
light. Watering can be done weekly during
the
summertime, if the weather is sunny enough, with a little
fertilizer added. Kept this way, plants
will show a
healthy, although slow
growth. They are
frost hardy to -4° (-10°) C
Propagation: By
seeds, remembering that
seedlings dislike strong
light and
dry conditions, and need to be
repotted frequently. But plants are often
grafted to accelerate growth, as they
would generally take at least five years to reach
maturity on their own. However the grafted
plants are typically rather tall-growing, in comparison with plants on
their own roots, that are usually flatter to the
ground.
